[0086] like Figures 1 to 9 As shown, this embodiment provides a correction device for a battery cell 3. The correction device includes a main body (not shown in the figure), a support device 1, and a limiting device 2. The support device 1 is installed on the main body and is used to mount an image sensor (not shown in the figure) that collects the detection position of the battery cell 3. The support device 1 can drive the image sensor to move. The limiting device 2 is installed on the main body and is used to limit the position of the battery cell 3. The limiting device 2 includes a limiting wheel 21 and a driving assembly 22. The driving assembly 22 can drive the limiting wheel 21 to move towards or away from the battery cell 3.

[0087] In this embodiment, an image sensor is used to acquire the detection position of the battery cell 3 and observe whether the position of the battery cell 3 has shifted. The image sensor is mounted on the support device 1, which can drive the image sensor to move, thereby adjusting the detection range of the image sensor and enabling the image sensor to acquire the detection range of the battery cell 3 from multiple angles, thus improving the accuracy of the battery cell 3 position detection. Limiting wheels 21 are located on both sides of the battery cell 3 conveying device to limit the position of the battery cell 3 and prevent the position of the battery cell 3 from changing. The drive assembly 22 can drive the limiting wheels 21 to move closer to or further away from the battery cell 3 to adjust the position of the limiting wheels 21 so that the limiting wheels 21 can limit the position of battery cells 3 of different sizes.

[0088] like Figures 1 to 4 As shown, in some embodiments, the drive assembly 22 includes a first drive member 221, a first support plate 222 and a second support plate 223. The limiting wheel 21 is mounted on the second support plate 223. The second support plate 223 and the first drive member 221 are mounted on the first support plate 222. The first drive member 221 can drive the second support plate 223 to slide along the first support plate 222, thereby driving the limiting wheel 21 to move along the first support plate 222 in a direction closer to or away from the battery cell 3.

[0089] In this embodiment, the first driving component 221 includes a stepper motor (not shown in the figure), two gears 224, and a toothed belt 225. The toothed belt 225 is sleeved on the two gears 224. The second support plate 223 is connected to the toothed belt 225, and the driving end of the stepper motor is connected to the gears 224. The stepper motor drives the gears 224 to rotate, the gears 224 drive the toothed belt 225 to move, and the toothed belt 225 drives the second support plate 223 to move, thereby enabling the second support plate 223 to drive the limiting wheel 21 to move, thus adjusting the position of the limiting wheel 21.

[0090] Specifically, the first support plate 222 is provided with a slide rail 222a, and the second support plate 223 is provided with a slider 223a. The slider 223a cooperates with the slide rail 222a and can slide along the slide rail 222a, so that the second support plate 223 can move along the first support plate 222. The bottom wall of the slide rail 222a is also provided with multiple adjustment holes, and the slider 223a is provided with mounting holes. The mounting holes can be set opposite to any of the adjustment holes. The mounting holes and adjustment holes are connected by connectors to fix the first support plate 222 and the second support plate 223.

[0091] like Figure 1 and Figure 4 As shown, the limiting device 2 also includes an adjusting plate 23 and a mounting plate 24. The limiting wheel 21 is disposed on the adjusting plate 23, and the mounting plate 24 has a mounting groove. The adjusting plate 23 is installed in the mounting groove and can move relative to the mounting plate 24. The mounting plate 24 is mounted on the second support plate 223. Along the direction of the limiting wheel 21 towards or away from the battery cell 3, the two ends of the mounting plate 24 are provided with set screws 241. One end of the set screw 241 passes through the side wall of the mounting groove and abuts against the adjusting plate 23. By adjusting the length of the set screws 241 at both ends of the mounting plate 24 screwed into the side wall of the mounting groove, the position of the adjusting plate 23 in the mounting groove is adjusted, thereby achieving fine adjustment of the limiting wheel 21. After the positions of the adjusting plate 23 and the mounting plate 24 are adjusted, they can be fixed by connection.

[0092] Multiple limit wheels 21 can be installed.

[0093] In some embodiments, the limiting wheel 21 is fitted with a rubber sleeve, which contacts the battery cell 3 to prevent the limiting wheel 21 from being too hard and causing damage to the battery cell 3.

[0094] like Figures 5 to 9As shown, in some embodiments, the support device 1 includes a third support plate 11, a fourth support plate 12, and a fifth support plate 13. An image sensor is mounted on the fifth support plate 13 and is movable along the fifth support plate 13 in a first direction X. The fifth support plate 13 is mounted on the fourth support plate 12. The fourth support plate 12 is mounted on the third support plate 11 and is movable relative to the third support plate 11 in a second direction Y. The third support plate 11 is mounted on the device body and is movable relative to the device body in a third direction Z. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0095] In this embodiment, the third support plate 11 is installed on the main body of the equipment, the fourth support plate 12 is vertically installed on the third support plate 11, and the fifth support plate 13 is vertically installed on the fourth support plate 12. The fifth support plate 13 is vertically arranged. Figure 7 As shown, the first direction X is the length direction of the fifth support plate 13 after the support device 1 is assembled, the second direction Y is the length direction of the fourth support plate 12 after the support device 1 is assembled, and the third direction Z is the length direction of the third support plate 11 after the support device 1 is assembled. In this embodiment, the relative movement between the support plates enables the image sensor to move along the first direction X, the second direction Y, and the third direction Z, thereby adjusting the detection range of the image sensor.

[0096] Specifically, such as Figures 7 to 9 As shown, the fifth support plate 13 is provided with a first adjustment part 131 and a first connecting part 132. The first adjustment part 131 extends along the first direction X. The image sensor is mounted on the first adjustment part 131 and can move along the first adjustment part 131 in the first direction X. The fourth support plate 12 is provided with a second connecting part 121, which is connected to the first connecting part 132.

[0097] In this embodiment, the first connecting portion 132 is located at the end of the fifth support plate 13. The first connecting portion 132 is a groove structure, and the second connecting portion 121 is a hole structure that penetrates the fourth support plate 12. One end of the connector passes through the second connecting portion 121 and is fixed to the first connecting portion 132, thereby connecting the fifth support plate 13 and the fourth support plate 12. The first adjusting portion 131 can be an elongated hole structure, allowing the connecting portion of the image sensor to slide along the first adjusting portion 131. After determining the position of the image sensor adjustment, the connecting portion of the image sensor can be fixed to the first adjusting portion 131 by the connector.

[0098] like Figure 6 and Figure 7As shown, the fourth support plate 12 is further provided with a second adjustment portion 122 extending in the second direction Y, and the third support plate 11 is provided with a third connecting portion 111. The second adjustment portion 122 is connected to the third connecting portion 111 and can move relative to the third connecting portion 111 in the second direction Y. In this embodiment, the third connecting portion 111 is a hole structure penetrating the third support plate 11, and the second adjustment portion 122 is an elongated hole structure. The connector can pass through the third connecting portion 111 and connect to any position of the second adjustment portion 122 to realize the connection between the fourth support plate 12 and the third support plate 11. By setting the second adjustment portion 122 as an elongated hole structure, the position of the fourth support plate 12 relative to the third support plate 11 can be adjusted in the second direction Y, thereby realizing the adjustment of the position of the image sensor in the second direction Y.

[0099] like Figure 6 As shown, the third support plate 11 also has a third adjustment part 112 extending in the third direction Z. The device body has a fourth connecting part, and the third adjustment part 112 is connected to the fourth connecting part and can move relative to the fourth connecting part in the third direction Z. In this embodiment, the third adjustment part 112 has an elongated hole structure, and the connector can connect the fourth connecting part and the third adjustment part 112 at any position to realize the connection between the third support plate 11 and the device body. By setting the third adjustment part 112 as an elongated hole structure, the position of the third support plate 11 relative to the device body can be adjusted in the third direction Z, thereby realizing the adjustment of the position of the image sensor in the third direction Z.

[0100] like Figure 8 As shown, the support device 1 also includes an adjustment ruler 14, which is mounted on the fifth support plate 13 and extends along the first direction X to determine the adjustment position of the image sensor. In this embodiment, the adjustment ruler 14 is located on both sides of the first adjustment part 131. The adjustment ruler 14 is provided with an adjustment scale, which can be used to adjust the distance that the image sensor needs to be adjusted. The adjustment distance can be obtained by direct observation, without the need for manual measurement with calipers, making the measurement more convenient.

[0101] In the above embodiments, the connecting component can be a screw, bolt, or similar component.

[0102] like Figures 10 to 13 As shown, this embodiment also provides a method for correcting the polarity of the battery cell 3. The method includes:

[0103] An image sensor is used to detect whether the position of the battery cell 3 has shifted. If a shift occurs, the shift value is calculated.

[0104] The main grid line 31 on the battery cell 3 is set as the Y-axis reference line of the battery cell 3, and the fine grid line 32 on the battery cell 3 is set as the X-axis reference line of the battery cell 3. The first detection line 4 is placed on the main grid line 31, and the second detection line 5 is placed on the fine grid line 32. The center point of the main grid line 31 and the fine grid line 32 is determined. The offset of the first detection line 4 from the center point of the main grid line 31 is calculated, and the offset of the second detection line 5 from the center point of the fine grid line 32 is calculated. The offset of the battery cell 3 in the X-axis and Y-axis directions is obtained.

[0105] Let a1 be the center point of the first adhesive dot 33 on the battery cell 3, b1 be the center point of the first fine grid line where the first adhesive dot 33 is located, a2 be the center point of the second adhesive dot 34 on the battery cell 3, b2 be the center point of the second fine grid line where the second adhesive dot 34 is located, connect a1 and a2 to get the straight line a1a2, connect b1 and b2 to get the straight line b1b2, calculate the angle difference between the straight line a1a2 and the straight line b1b2, and obtain the offset of the angle of the battery cell 3.

[0106] The offset of the battery cell 3 in the X and Y axes, as well as the offset of the angle of the battery cell 3, are input into the controller to control the battery cell 3 to perform correction.

[0107] In this embodiment, an image sensor captures an image of the battery cell 3 to detect whether its position has shifted. If the position of the battery cell 3 has not shifted, it can proceed to the next process. If the position of the battery cell 3 has shifted, the image sensor transmits the shift signal to the controller, and the controller program calculates the shift value. The method for calculating the shift value of the battery cell 3 is based on the distance between a line and a point, and the angle of the line connecting the points, to obtain the shift values ​​of the battery cell 3 in the X-axis, Y-axis, and angular directions.

[0108] Specifically, the main grid line 31 on the solar cell 3 is assumed to be the Y-axis reference line, and the fine grid line 32 on the solar cell 3 is assumed to be the X-axis reference line. The first detection line 4 in the Y-axis direction is placed on the main grid line 31, and the second detection line 5 in the X-axis direction is placed on the fine grid line 32. The center points of the main grid line 31 and the fine grid line 32 are determined, and then the positions of the center points determined by the main grid line 31 and the fine grid line 32 are compared with the positions of the first detection line 4 and the second detection line 5 to obtain the offset of the solar cell 3 in the X-axis and Y-axis directions.

[0109] After the adhesive is printed onto the battery cell, the center point a1 of the first adhesive dot 33 and the center point b1 of the first fine grid line containing the first adhesive dot 33 are detected by an image sensor. Similarly, the center point a2 of the second adhesive dot 34 and the center point b2 of the second fine grid line containing the second adhesive dot 34 are detected by the same image sensor. Connecting points a1 and a2, and connecting points b1 and b2, yields two straight lines. If the position of the battery cell shifts before adhesive printing, the adhesive dot and the fine grid line will not be aligned during printing, resulting in an angular difference between the two lines. This angular difference is the offset value of the battery cell 3. The calculated offset value is written into the program, which then feeds a drive signal back to the controller. The controller then controls the motor to correct the deviation of the battery cell 3.

[0110] Among them, the first adhesive dot 33 and the second adhesive dot 34 are adhesives that serve an insulating function.

[0111] Specifically, such as Figure 11 and Figure 12 As shown, the correction method further includes: after obtaining lines a1a2 and b1b2, connecting point a2 and point b2 to obtain line a2b2. Lines a1a2 and a2b2 form an angle t1, and lines b1b2 and a2b2 form an angle t2. The difference between angles t1 and t2 is the offset of the angle of the battery cell 3. In this embodiment, if lines b1b2 and a2b2 are parallel and angles t1 and t2 are equal, the glue printing position is correct, indicating that the angle of the battery cell 3 has not shifted. If angles t1 and t2 are unequal, the glue printing position has shifted, indicating that the angle of the battery cell 3 has shifted, and the difference between angles t1 and t2 is the angle offset value of the battery cell 3.

[0112] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
